Turns on with no image and the LCD lamps start blinking | 10 micron capacitor shorted on the LCD board | Disconnect the flat cables from the LCD and test, if the lamps remain stable, reconnect one side and test, the side that gives the defect, test the capacitors on the LCD board, normally those larger than 10 microns short out and cause this defect | Djalma Moreira |

Sometimes it would work normally, then if it turned off, it would turn on, but when it turned on, the LED would blink the next day until it worked. | D-810 and photo coupler | I replaced and ran to another one | Antonio Carlos (Eletrônica Renascer) |

Device without sound. good sound output, everything turns on, but tsound is no audio output | Resistor r139 (47r) open, it is close to ic14 which is pt2314, and close to the audio inputs | In this case, just changing it did the trick. | Romildo Behrend Schwartz |

Turns on, shows an image and then turns off the LEDs, the sound remains normal | It seems to be a defect on the inverter board, I changed the r52 on this p.c.i from 470k to 100k but it didn't solve it. | I searched the net and found how to disable the protection of the i.c ssl100sn, pin 02 put a 1k resistor to ground and if the defect persists put pin 8 a 1k resistor to ground too. follows as it is on the net: "I have a great day, I'm new and I just subscribed just to give another solution to the ssl100sn inverter circuit.. note that tsound is very little to say anything. information. well, the point is that searching one forum to another and after doing tests, I can find the integrated pin which is the olp and the ovp. The olp is located on pin 2 of the ssl100sn. in case the television turns on, it is heard and not seen) the ovp is located on pin 8 of the same integrated in the same way, to be able to cancel the protection, simply place a resistance of the same value (1kΩ) in the case. of having pin 2 grounded and continuing to fail. Well apparently that was all, for now, I would like to know your opinions, suggestions or also if you have already found the answer. | MIGUELTV |
